For my first real attempt to make full out heavy dubstep song I want it to be revolved around an idea. So i decided to pick a movie. The newest movie comming out that i think is going to be crazy good and a hit is Pacific rim. In the beginning of this video theres a very metallic sound with a long attack. Im trying to recreate that for part of the song and i have other things im going to put in, such as movie vocals and a glados voice im going to make melodyne. The movie comes out in over a months time and would want to try finish it then.
I need help with looking for a sample of a deep horn or string(maybe a library). Then ill resample it a couple times to get that gritty bassy sound like in the movie. If i cant then ill just have to work around with massive or fm8 with a bright saw patch and go from there.
If you know any libraries with sounds very cenematic samples or have an idea to make a a gritty sound it would be much appreciated. After its done ill release the full project and presets with it.

Heres the video with the metallic string/horn i was talking about. Starts at 0:07, 0:24, 0:54, 1:48, 2:06, 2:26
